    Default Celestion Ditton 44 - External Crossovers?

    With my pair of 44 cabinets needing to be rebuilt would there be any benefit to moving the crossover externally, fitting three sets of binding posts (Cardas CCBP) instead of the usual one and wiring those up to each speaker?

    I'd say yes. Give it a go.

    Nice quality speakers. Also, if you haven't already, swap out any aging electrolytic caps.

    Thanks for the reply I wanted to move them from the back of the sub but couldn’t find anywhere internally to put them so hoped this would be a good alternative.

    Is there a recommended distance from the speaker when going with external crossovers?

    They will be rebuilt before it all goes back together, now things are starting to open up again I can get this project moving.

    Hi Ben, just to play devils advocate....
    If you are going to go active, I can see the benefit however if passive, the probably small benefit of having an external crossover should be weighed against the extra cost, additional boxes, speaker cable, floorspace required, general untidyness and probably a reduction of resale value.
    I only say this as I remember when kevin introduced the IBX internal xover version of the living voice avatar and thinking how much less fussy they were compared to the external covers of my obx.

    Hi Graham.

    Playing devils advocate is fine with me, it’s nice to be able to bounce ideas off people and chat about pros and cons.

    The speakers wouldn’t be going active, I would just be removing the crossover from directly behind the woofer. I agree it’s a lot less fussy with everything inside the box but with the 44’s internal space is a commodity.

    The extra boxes wouldn't be much of an issue as the room is quite large, I was thinking about making them out of reclaimed hardwood with dovetail joints and an acrylic lid, then French polishing the wood to help with the untidiness factor.

    Value wise is a tough one. The speakers are in good condition, the tweeter will be rebuilt as will the crossovers, albeit sympathetically. But the cabinets are rough. I will be remaking those so the patina will be lost in that respect.

    Cap values for the 44 cross over has been discussed zillions of times, they all come to the same conclusion, stick to the original values, just a friendly piece of advice to stop you from going down a rabbit hole.

    Cheers Andrew but we weren’t discussing cap values. Just the idea of moving the crossover from inside to outside of the cabinet

    Hi Ben,
    Your approach sounds logical to me, so good luck with the venture

    I've often thought about pimping up a good quality pair of vintage speakers to show that fundamentally they can still hold their own against more recent designs in most respects except maybe pure SPLs. Good luck with this.
